X can be any number in the graph as long as it is on the x-axis therefore you can put x as -1,0 and 1. Then you would need to replace the ‘x’ in the equation so it would look like y=-2*1+3. You replace ‘x’ with every number you put in the x boxes. Then just solve the equations
y=-2*1+3 Y=-2*0+3 Y=-2*-1+3 They would give you the y axis coordinates so then you just put them together for the middle column.
